Tuomas Virtanen - Audio processing software

This web page contains some audio processing software that has originated from my research work. The currently available tools focus on one-channel source separation and efficient algorithms for non-negative representation of audio. Information about my other activities can be found on my research web page.

The algorithms can be used and modified for non-commercial purposes - see the legal notice. Please visit this web page for updated versions of the algorithms and other updates.

Please report (tuomas.virtanen@tut.fi) if there are any problems with the algorithms. I am also interested in getting feedback about the algorithms, so feel free to e-mail me!
